Police in Huainan, Anhui Province say they’ve finally closed an assault case after detaining the wrong twin brother a total six times, media reported Tuesday.
Officers arrested the suspect surnamed Hu on August 18 for his connection in the assault of a local resident four years earlier.
Four other suspects involved in the beating have served jail terms.
Police said in their pursuit for Hu they had mistakenly tracked down his twin brother six times.
After interviewing local residents, police determined that Hu has features distinguishing him from his brother, such as a mole on his lip and tattoo on his right arm.
Hu told police he had been using his brother’s ID for years and thought officers had “forgotten about him.”
